In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: Was Montana the quarterback during each of Walsh's Super Bowl wins? Passage:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.

Example Input: Question: In what year did the wrestler who's neck the Godwinns tried to break begin his career? Passage:In 1996, Canterbury was reunited with Knight, who had been renamed Phineas I. Godwinn. The duo were portrayed as being cousins (later brothers) and were collectively known as "The Godwinns". The two were faces and were managed by Hillbilly Jim. They began to feud with the Body Donnas with Phineas having a crush on Sunny and signed her as their manager. They would beat the Body Donnas for the WWF Tag Team Championships. Eventually Sunny turned on them costing them their titles. The Godwinns feuded with the now heel Smoking Gunns, in losing efforts. In 1997, the Godwinns began a heel turn dropping Hillbilly Jim as a manager and picking up Uncle Cletus. The Godwinns quickly won the tag titles a second time from The Headbangers and began a heated feud with the Legion of Doom, which saw the team attempt to break Road Warrior Hawk's neck. They eventually dropped the titles to LOD in a match on WWF Monday Night Raw that had LOD's career on the line. Soon after that match they attacked and fired Cletus.
